GUITAR OR OTHER SIMILAR STRINGED INSTRUMENT.

SPECIFICATION forming part of Letters Patent No. 425,864, dated April 15, 1890. Application filed November 26, 1889. Serial No. 331,597. (No model.)

To all whom it may concern.-

Be it known that I, HENRY J. OAsANovA, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Guitars. or other Musical Instruments, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

This improvement applies to guitars, violins, bass-viols, and other instruments of this class having a case with musical strings stretched over the same.

It consists in the insertion within the ordinary case of another case having the same general form, but of so much smaller dimensions as to leave space between them at all sides.

The invention will be described as applied to a guitar,

Figure I is a front view of a guitar with part of the front board of the outer case broken out to show the inside. Fig. II is a front view of the interior case. Fig. III is a detail longitudinal section at III III, Fig. I.

The outer case is of the usual or any suitable form, having a back board 1, a face or front board 2, and side board 3, conneetin g the margins of the front and back boards, as usual. 4 is the finger-board, in which no novelty is claimed. The inner case has a bottom plate or board 5, a front or face board or plate 0, and a side plate or board 7, extending around the margins of the back and front and secured to the same. Bottom, front, and side 5 6 7 of the inner case are substantially parallel with the same parts 1 2 3 of the outer case,

the only points of attachment being at the cross-bars 8. In my preferred construction the bottom 5 and side 7 are of metal and secured at the corner by soldering, the front 6 being preferably made of wood and secured by nails passing through the metal side. The whole orany part of the interior case may, however, be made of metal, wood, or other suitable substance.

8 are transverse bars extending the whole interior width of the outer case, and secured to the front boards 2 and 6 and serving to connect the cases together.

0 are ribs serving to stiffen the front board 6.

10 is the orifice in the front board 6, and 11 is the orifice in the front board 2, of the outer case. The orifice 10 is shown circular and the orifice 11 elongated; but I do not confine myself to any particular form or size for these orifices.

2 is the bridge over which the strings are stretched, said bridge being attached to either or both of the front boards 2 6. As shown, it is secured toboth of the frontboards, f0rming a connection between them, and serving to throw both of them into vibration by connection with the strings.

I claim as my invention The combination, in a musical instrument, of the outer case 1 2 3 with orifice 11 and the inner case 5 6 7 with an orifice 10, in connection with the orifice ll of the outer case.

HENRY J. OASANOVA.
